a. the application of net-filter as follows: 
 Net-filter especially for municipal water supply, power plants, metallurgical industry, water recycling, sewage treatment and other high flow water filtration applications. 
 Mainly by the filter net-filter unit, controller, solenoid valve, three hydraulic valve. (Beijing) Technology Co., Ltd. Lauren filter without filter, a simple structure, high efficiency, small footprint, etc., can effectively remove suspended solids. 
 b. net-filter set features: 
 1, the net-filter uses patented technology within the mechanical structure, to achieve a real sense of the high-pressure backwash function, can be easily and thoroughly clean the filter retention of impurities, cleaning no dead ends, the flux without attenuation, protection of the filtration efficiency and long service life. 
 2, the net-filter wedge filter used 304,316 L stainless steel, high strength, high accuracy, corrosion resistance, high filtration precision of up to 25 microns. 
 3, the net-filter and strain through its own search capabilities, automatic backwash, the water quality can respond to fluctuations in the unstable, without human intervention. 
 4, the net-filter less wearing parts, no consumables, low cost of operation and maintenance, operation and management simple. 
 5, net-filter run precision, based on the accuracy of different flexibility to adjust the water and filter backwash pressure time and time settings. 
 6, the net-filter backwash process, the individual (s) in order to filter backwash operation; to ensure that the filter safe, efficient cleaning, while other filters are not affected and continue filtering. 
 7, the net-filter sewage pneumatic valve, short duration backwash, backwash water consumption, environmentally friendly economy. 
 8, the net-filter design reasonably compact, small footprint, flexible installation of mobile. 

 c. the technical parameters of net-filter: 
 Working pressure: ≤ 1.0Mpa (For higher working pressures, please specify when ordering) 
 Pressure loss of power: ≤ 0.015Mpa 
 Filtration: 0.8 mm (0.2 ~ 3.5mm accuracy range can be manufactured) 
 Maximum working temperature: ≤ 100 ° C
